914 Foundation Repair in Scarsdale, NY
Scarsdale’s housing stock is old: the typical home was built around 1943, and more than half of homes pre-date 1950. Older foundations of that age are where most waterproofing, drainage and sump pump calls come from. The repair method depends heavily on the type of foundation and soil. An independent structural engineer can help you compare proposals, which is worth considering for any job involving bowing walls, piers or underpinning.

- The village’s own sewer-compliance program notes that seasonal groundwater combined with poor foundation drainage or failed waterproofing leads to sump pumps being wired into the sewer, which is not allowed. [source]

What it costs
Foundation repair spans a very wide range. HomeBlue's White Plains guide gives $2,800 to $29,500 for major repairs involving underpinning or piles and $2,400 to $4,700 for minor crack repair with basic waterproofing, but notes the range is broad because every job differs. A modeled Yonkers estimate (RenoVetted) puts pier or repair-point work around $528 to $2,112 per point, or about $4,200 to $16,900 for an 8-point job. National HomeGuide figures put crack injection at $250 to $800 and bowed wall repair at $5,000 to $15,000. Only a structural evaluation can tell you which applies to your home.

Frequently asked questions

Does Scarsdale require a permit for this work?

Is a hairline crack in my foundation serious?
Thin vertical cracks in poured concrete are common from shrinkage. Horizontal cracks, bowing, cracks wider than a coin edge, or cracks that leak or grow should be looked at by a foundation specialist or structural engineer.
Do I need a structural engineer?
For bowing walls or significant settlement, an independent engineer's report can help you compare contractor proposals objectively.
